Except that it IS broken. That's why we're having this discussion. The "Dear Github" post is trying to say "the process of making OSS is broken" but is asking for a software solution to a human problem.
Linus' approach to project management is to chase away everyone by being a "gentleman sausage". He has the sheer technical competence to succeed in spite of this, but it's not a successful approach for most people, and dudes attempting to emulate Linus chase out the decent human beings.
Making the process of making OSS sustainable for mere mortals will go a long way to making more OSS.
Not so. The "Dear Github" post is all about bug tracking facilities in github, nothing more. Previous versions of Github had a more functional issue tracker - it went largely ignored and github wisely removed the unwanted cruft from their code base. Github is not JIRA. OSS projects are free to use whatever bug-tracking facilities they choose. Just like everyone else. I would like to see better API's from github to support this.
On to Linus. There are 12000 contributors to the linux kernel, If Linus sucks at anything, it would be his ability to "chase away everyone". You seem to be of the opinion that if there were more than 12k Linux would somehow be "better". This is entirely conjecture on your part, and many would argue that Linus is fact too lenient as it stands.
